FIELD: process engineering.
SUBSTANCE: invention relates to heat supply for chemical conversion, particularly, to production of olefin, especially, styrene by dehydration of ethyl benzene. Proposed method comprises: overheating of heat transfer fluid, heat transfer from said overheated fluid to initial reaction mix, and separating said heat transfer fluid into first and second parts. It includes also increasing the first part pressure, circulating said first fluid part at pressure to overheating stage and feeding second heat transfer fluid part into initial reaction mix.
EFFECT: operation at low steam-to-oil ratio and temperature.
